I would also like to be able to tag calendar events with keywords then bring up a list of events that match a given keyword or suite of keywords. I have a bunch of presentations that I am giving on my calendar. I don’t remember what all of them are. I would like to search for events with the keyword: presenting and see the list. I have to go through my calendar, week by week, to look at the up-coming presentations.
Also, I want to be able to bind email to a calendar event. I have an email request to present at a given time and place. I want to be able to attach that email to the event.
Finally, I should be able to attach, flag, tag events which I do not control but have been invited too. I should be able to add my own notes for myself, my own details, etc. even though I do not control the invite.
